m3358557 ZZ 1G so that` as the brush 'blocks roqress 9 f l* lili thro-1L i the machine, the teeth l5 will dig deeper and deeper into said blocks.A

lfhe bearings ll are also laterally adjustable relative to the medial plane of the block clamps. as indicated in Fig. 3, and the vertiral medial piane of shaft l2 is laterally oilyl' tive to the vertical medial plane of the block: holders, indicated in Fig. 3, so that the teeth l5 will at all timesI enter the upper tace. oi the brush block, distin- Iauished t'rom entering the side or vertical 'lace ci such block, and will emerge from the brush block at its side instead of from the upper face.

Shaft l2 carries a worm 6G which meshes with a 'crm Wheel (il carried by a shaft 62 supported in vertically adjustable bearings 63. iilhalt (i2 also carries a sprocket Wheel '6d- Whicli mirries a sprocket chain 65` engaging a sprocket wheel t6 on shaft 20', the arrangement being such that upon rotation of drun'i it. chains 18 will beslowly ad- 'va d in the direction indicated by the row in Figs. l and 2.

Any suitable means may be 'provided for 'ng the raker teeth 15 in the drum lll. n lfiffs hvland 5, l show a series of rings 70 adapted to be clamped between heads 7l by clamping bolts 72. lilach of the rings 70 is provided ou each end with 'adial notches 73 adapted to receive and clamp the raker teeth l5 and by a suitable relative setting of the various rings any kdesired the teeth may be obtained.

lhe ralier teeth are preferably somewhat rounded and blunt et their ends so as to remove the pith iroin the brush blocks Withstaggering of rout cutting or breaking the tough fiber.

The operation is as follows: As the brush clamps successively reach the left hand end o'l the machine (Fig. l), cam 53 is engaged by the roller 55 so that the clamping jaws are separated to permit 'the placin0r of a brush block in the clamping head. lllst before the brush 'blocks reach the initial end oi" the drum le, the end of cam 53 is reached, and the brusl. blocks are thus firmly clamped in the clamping head. At about the time the brush block reaches the initial teeth of the drum le, pinion 23 engages rack Q4 and, shoe leaves 26 so that, at about the time the raker teeth 15 begin to engage the brush bloeit', the said brushblock is 4rotated about an axis Isubstantially at lright angles .to the line of transportation of the brush block and substantially, although not quite, at right angles to the axis of the drum 14.

As the blocks proceed through the 1nachine, the teeth 15 enter the upper face of the block, gouge out a small quantity or' pith and discharge it from the side ofthe block, the teeth entering more and ymore deeply until, whenI the blocks reach the final end of .the drum, a desireddepth of digging has been reached and aV desired length of the embedded tough fibers of the block exposed. As the brush block emerges from beneath drum 14, cam 5l is reached by roller 55 and the completed brush is released from the raking movement between. the clamping'l member and raking member duringraking operation. t
